The inflammation increases the risk of having a myocardial infarction - a heart attack, as well as a stroke, and peripheral vascular disease which is where there is severe pain in the lower legs.

这种炎症会增加心肌梗死的发病风险，即平时所说的“心脏病发作”，同时中风、周围血管疾病的发病风险也会增加，其中周围血管疾病的最常见表现是下肢剧烈疼痛。

Thus, the parasympathetic causes slower heart rates and respiratory rates, sleep, increased gastrointestinal track motility, increased peripheral vascular flow, blood flow to all cells, liver and kidneys, and venous return to the heart.

因此，副交感神经引起心率和呼吸频率减慢、睡眠、胃肠运动和周围血流增加、血液流向所有细胞、肝脏和肾脏以及静脉血回流到心脏。
